99% of the requests are fast and can be served far below 300 ms. Only
a few type of requests need to stream lots of data. Do you really think that
unicorn isn't a good choice in this case and I should consider switching to
something else (Rack::Timeout + Rainbows!, Puma or whatever) just for the
sake of that 1%?
